从亲本纯系获得血液样品，所述亲本纯系代表目前在美国可获得的大部分商业肉型（肉鸡）和白色蛋层系。从每个品系的血液混合物中提取DNA，并产生该品系的DNA指纹图案特征。此外，DNA指纹代表野生原鸡和两个随机饲养的对照种群。进行了三项分析：1）在肉仔鸡父系、原鸡和一个对照系之间; 2）在肉仔鸡母系、原鸡和一个对照系之间;和3）在白色蛋蛋鸡的亲本系、原鸡和第二对照系之间。带宽共享水平进行了计算，提供了一个估计的遗传多样性线之间。结论是，目前，肉鸡父系、肉鸡母系和白色产蛋蛋鸡的亲本系构成了美国大部分商业育种群体，它们含有相当大的遗传多样性。
Blood samples were obtained from parental pure lines representing a large majority of commercial meat-type (broiler) and white egg layer lines presently available in the USA. From blood mixes of each line, DNA was extracted and a DNA fingerprint pattern characteristic of that line was produced. Additionally, DNA fingerprints representing wild jungle fowl and two randombred control populations were produced. Three analyses were conducted: 1) among broiler sire lines, jungle fowl, and one control line; 2) among broiler dam lines, jungle fowl, and one control line; and 3) among parental lines of white egg layers, jungle fowl, and the second control line. Bandsharing levels were calculated, providing an estimate of genetic diversity among lines. Conclusions were that, at present, broiler sire lines, broiler dam lines, and parental lines of white egg layers that make up the majority of commercial breeding populations available in the USA contain a considerable reservoir of genetic diversity.
